In the Control phase of DMAIC we want to make sure that we are prepared for implementing whatever changes we have decided on in the improve phase of DMAIC.
When maintaining solutions, the type of control you should use is primarily determined by where your process is located on the standardization / throughput matrix.
Process Characterization’s purpose is to provide objective evidence that critical product parameters and associated process parameters are consistently capable of meeting customer requirements.
Identify non-normal data Analyze how to transform non-normal data
Process Capability & Performance (Pp, Ppk, Cp, Cpk) are indicators of the specification relative to process dispersion and process centering, respectively.
